XRay GTX Carbon Centre Mounting Rear Brace XR354258

The XRay GTX Carbon Center Mounting Rear Brace - Short - Flat Chassis, part number XR354258, is a short carbon rear top deck brace for a flat-chassis layout. It connects the centre two-speed assembly with the rear aluminium brace mount, creating a structural link across the rear section of the chassis.

The compact design is intended to maintain the balance of rear chassis flex while supporting drivetrain stability. By controlling how the rear section flexes, the brace contributes to predictable handling, rear stability and consistent traction across changing track conditions. These characteristics help keep the relationship between the centre assembly and rear brace mount consistent during use.

Construction And Chassis Function

Precision-machined carbon fibre provides the brace with rigidity, durability and a lightweight format. Its short profile is shaped around the flat-chassis arrangement, while the top-deck design keeps the connection between the centre two-speed assembly and rear aluminium mount compact. The component is suited to applications where rear flex balance and drivetrain stability are being adjusted together.

XR354258 is supplied as the short rear carbon mounting brace described here. It is a chassis component rather than a complete two-speed assembly or rear brace mount, and its role is to connect those areas while influencing the flex characteristics of the rear chassis. Suggested compatibility should be checked against the intended GTX flat-chassis setup before fitting.
